这与this question.

在模板中尝试类似的操作，并根据需要的组合将and条件更改为和/或（视情况而定）。

$args = array(
\'post_type\' => \'Book\',
\'tax_query\' => array(
    \'relation\' => \'AND\',
    array(
        \'taxonomy\' => \'Genre\',
        \'field\' => \'slug\',
        \'terms\' => array( \'Fiction\' )
    ),
    array(
        \'taxonomy\' => \'Media Type\',
        \'field\' => \'slug\',
        \'terms\' => array( \'eBook\' )
    )
)
);
$query = new WP_Query( $args );
